Title: Improvements in or relating to rotary mechanisms, more particularly internal combustion engines
IPC: F02B53/00
Filed: 1961-02-03
Abstract: 906,387. Rotary internal-combustion engines. CURTISS-WRIGHT CORPORATION. Feb. 3, 1961 [Feb. 5, 1960], No. 4175/61. Class 110(2). In a rotary four-stroke I.C. engine, a substantially triangular-shaped rotor 24, Fig. 1, eccentrically rotatable in an epitrochoid-shaped casing 12 includes on its end faces 26, 28, Fig. 2, adjacent the outer periphery arcuate grooves 60 joining the apices which mount spring- loaded sealing strips 62 and surrounding the shaft bearing 70, a circular groove 68 mounting a spring-loaded sealing ring 66. The former is to prevent the leakage of combustion gases from the engine combustion spaces 32 and the latter to prevent oil leakage. Passages 74 through the rotor adjacent each apex interconnect the spaces between the seals on opposite sides of the rotor. This prevents a build-up of pressure on one face of the rotor with consequent axial movement of the rotor and friction and wear between rotor end faces and associated casing end faces. On rotation of the rotor, the passages 74 connect the spaces between the seals to the intake port 40 to return combustion gases to the engine and so prevent pollution of the atmosphere. In a modification, the intake port is located as a peripheral port similar to the outlet port 44. In this case, a channel 80, Fig. 4, in a casing end wall adjacent the intake port 40a spans the sealing strips 62a.

Abstract: 1411716 Ignition systems BRUNSWICK CORP 26 Jan 1973 [4 Feb 1972] 4191/73 Heading F1B To ensure operation in the forward direction only, e.g. of a two stroke I.C. engine for outboard motors, utilizing a capacitor discharge ignition system of the breakerless type, the system includes two series-arranged SCR switches 8,20 triggered by pulses from first and second pulse generators 16, 17 and arranged so that only when the engine rotates in the forward direction will the pulse from the generator 17 render switch 20 conducting to allow the subsequent pulse from generator 16 to actuate switch 8 and allow the capacitor 3 to discharge through the primary coil 9 at the usual pulse transformer 5 to fire selectively the sparking plugs 2. Attempted reverse rotation of the engine will produce a pulse from the pulse generator 16 before SCR switch 20 is conducting, and hence this will block the pulse, preventing discharge of the capacitor. As shown, the pulse generators are formed, as an alternator 12 including an enginedriven rotor 13 carrying a pair of permanent magnets 14, and a pair of windings 16, 17 close coupled by separate cores 18. 19 to the magnets. The direction sensing winding 17 is connected in series with a blocking diode 25, and both are in series with a holding capacitor 27. A clamping diode 24 limits the maximum voltage applied across the gate-cathode circuit of the SCR switch 8, and transient protection capacitors 22, 23 are provided on opposite sides of a gate resistor 21.
